During the sweltering summer months, the last thing you want is for your A/C to break. However, if you do not get your AC unit serviced in line with the manufacturerโs schedule and you donโt act on any problematic signs swiftly, this is what could happen.
With that in mind, we are going to explore some of the different signs that your air conditioner needs to be repaired. If you notice any of these issues, get in touch with a professional sooner rather than later so you can avoid an expensive replacement.
- The system is blowing out hot air
One of the first signs that you need an AC repair service is when the unit is blowing out hot air. This may happen as a consequence of the refrigerant levels being low due to a leak in your system. However, it could also be due to an issue with your condenser.

- Your electric bills are higher than usual
If you are using roughly the same amount of air conditioning as usual, yet your bills are alarmingly high, this indicates that there is a problem. It may simply be that your AC is too old and inefficient. Other causes include leaks in the HVAC systemโs ductwork and a broken thermostat switch.
- Moisture around your AC system
Moisture around your AC system can indicate a refrigerant leak. Contact a professional immediately, as this liquid is poisonous. Hopefully, the issue is being caused by something less serious, for example, it could be water from a blocked or broken tube. However, you cannot afford to take any chances.
- Your AC smells funny when in-use
Your AC unit is not supposed to have a bad smell. If it does have a strange smell, there is an issue. If the smell is musty, it may indicate there is mold somewhere inside the ductwork or unit. If the smell is a strong burnt smell, it may be that there is a burned-out wire in the unit.
- Loud noises are coming from your AC unit
When the air conditioning unit is switched on, do you hear scraping, squealing, or grinding sounds? If so, this indicates there is an issue with a belt moving out of place inside the unit. If this is not rectified quickly, it can cause damage to other parts of the unit.
- Cool air is coming out of the AC very weakly
Although your AC may be blowing out cool air, it may not feel sufficient to keep the entire room cool. If the air is blowing very weakly, it is usually one of two things; either an issue with the ducts or a failing compressor. An experienced HVAC technician will be able to get to the bottom of this for you.
- Your AC thermostat is not working

The thermostat is the command center for your AC system. It communicates with the unit, informing it of how much cold air to generate. If your AC unit wonโt turn on or runs for small periods of time before shutting itself off automatically, this could indicate your thermostat is not working properly.
Donโt ignore these warning signs!
If you have noticed any of the signs mentioned above, do not simply bury your head in the sand. We know that an AC unit repair service is not something a lot of people budget for, but you will only face bigger expenses if you do not get the issue attended to as soon as possible.ย
